Android: Implement Woopra in App

Trying to add Woopra in my Android App but there is no SDK for Android provided.
Is there any way to add Woopra in Android App to log events?
Please help me on this if anybody have tried on this topic.
thanks in advance.

I'm Elie from Woopra. We're publishing an Android SDK this week. You can access it directly on our GitHub account:

We're still doing the final touches but you can always pull the updates.

Starting with the Android source code

I'd like to start looking into the Android source code. I'd like to start with the easiest place. Which is the easiest place to start with - any application / framework? Please suggest.

A simple google search would provide you appropriate results
Information on Android Open source website
http://source.android.com
Android Source code
https://android.googlesource.com

In the Resources section of the Android SDK site there are some tutorials that will walk you through some source code. Here is a link to the tutorial on creating a notepad application

I think it is better to start with any application first because that way you will know how it is applied.

Start at the Android | Developer Website: http://developer.android.com/.
Under the "Resources Tab", you'll find useful example applications.
Make sure you installed Eclipse and the Eclipse Android Plugin. Than you ca create a new android project (File > New... > Other... > Android Project) in Eclipse and check "Create Project from exisiting Example". The Api Demo Application is great.
You should watch some Videos of Romain Guy, too, he's a coding genius.

How do I see the core Android classes?

I am trying to look inside a couple of Android core classes to see about overriding some methods. I have looked into getting the Android source code, but the process described on the Android dev site is all about installing and setting up some kind of development environment. This is not necessary to me. I just want to open a class or two in a text editor and look at its contents. Does anyone know if this is possible without going through the multitude of steps described on the Android dev forums?

The easiest way is to use Google Code Search. You just have to try a search like Activity.java android and you can see the source code of that class. It even has an outline inspector:

You can download the entire source with git our just look it up as a reference on the git site. Here is a link to the sdk code:
https://android.googlesource.com/platform/frameworks/base

Another option is to use http://grepcode.com/ and perform a search such as "android ViewGroup". I've really enjoyed the style of using grepcode.
